Question Link Given a positive integer B, evaluate the largest integer a. The value of a * (A + B) is the number of complete integers, 1 Solution: If we set the maximum common divisor of A and B to G, the maximum common divisor of A and A + B is also G, because the maximum common divisor has the property: gcd (A, B) = gcd (A, A + B) In this way, we can further simplify a * (a + B) = G ^ 2 * A

First, let's briefly introduce the Roman numerals. Seven roman numerals are taken from Wikipedia: I (1), V (5), X (10), L (50), and C (100) D (500), and M (1000 ). Any positive integer can be expressed according to the following rules. It should be noted that there is no "0" in the number of Rome, and it has nothing to do with the carry system. Generally, it is considered that a number in Rome is only used for counting, rather than computing. Repeat s

Problem Description: Given a positive integer n, break it into the sum of at least, positive integers and maximize the product of those inte Gers. Return The maximum product you can get. For example, given n = 2, return 1 (2 = 1 + 1); Given n = ten, return 36 (10 = 3 + 3 + 4). Note:you may assume, N is not less than 2. Hint:1) There is a simple O (n) solution to this problem.2) You may check the breaking results for n ranging from 7 to discover the

Merges the elements in an array into an integer and outputs the smallest integer. For example, the array {32,321}, the minimum is 32132, the array {100,22,199} has a minimum of 10019922 ...This is a face test, or share my method. Because the merging of arrays may be out of bounds, the method of using integers is not feasible. My idea is to sort the array as needed, for example, before 32,321, 321, 32 after

Integer partitioning is a more typical recursive problem: dividing an integer n n n into a series of numbers that are not more than M m.For example, if n=5 n = 5 n=5, m=4 m = 4 m=4, the partition can be: {4,1}, {3,1,1}, {3,2}, {2,1,1,1}, {2, 2, 1},{1,1,1,1,1}. A total of 6 combinations. If as long as the total number of output division, online reference more, also easy to understand parity.If you also requi
